Just changed my press from 2 1/2" to 3 " shells as I bought a Short Kit that is supposed to allow one to load either with minimal fuss. Everything went as planned until the last station the final crimp setting.I finally worked it out after calling MEC customer service . Very sensitive to fine adjustments. Tomorrow I'll try the short kit to see if it works. As .410 shells are now scarce and expensive I'll just load up a couple hundred. I picked up a flat of AAHS for the hulls a couple years ago. Got lots of shot ,wads ,primers and powder.
